  • The tiles were manufactured using a mixture of the TK material(a raw material in making tile) and Cu-Cr-Ag impregnated activated carbon(ASC Charcoal). The extraction character of heavy metals in making tile was evaluated and the manufacturing conditions of tile were studied. The heavy metals in the mixture-before and after the tile was production of tiles was successful and as a result of heavy metal analysis, the tile showed that the concentration of heavy metal after the production of tiles was lower than that of the before one. The concentration of eluted heavy metal by acidic and basic solutions was low and the quality of the produced tile was similar to the commercial one. The result of this study suggested that the waste ASC charcoal was used to produce good tiles and it also might reduce soil pollution.

  • Defects such as falling and cracking of tiles installed in the bathrooms of apartment houses are frequently occurring. Therefore, in order to solve this problem, the A/S cost of construction companies and consumer complaints are increasing. The causes of tile defects include problems such as the selection of tile adhesive and lack of adhesive strength, the carelessness of the installer, the base surface, and the absorption rate of the tile. Therefore, in this study, an adhesive construction method using tile adhesives with high resistance to deformation of floors and tiles was studied. In addition, the properties and construction methods of tile adhesives were evaluated.

  • The sediment in the highly contaminated Gamjeon brook was collected, mixed with the raw material of the tile, and then the commercial tile was produced using the mixture. The concentrations of the heavy metals in the mixture-before and after the tile was produced-were analyzed and the effects of the acid solution on the produced tile were examined. The production of the tiles was successful and the result of heavy metal analysis showed that the concentration of Fe was the highest and that of Cd was the lowest The amount of heavy metal in the sediment - the raw material of the tile mixture was more than that of the produced tile. The elution concentration of the heavy metal by the acid solution(pH : 4 - 7) was low and the quality of the produced tile was better than the commercial tile. The result of this study suggested that the contaminated sediment was removed to produce good tiles, therefore the water pollution and soil pollution were reduced.

  • Since the seventies and the oil crisis, energy-saving measures have led to a reduction in the ventilation of room. The use of synthetic materials which emit various chemical substances had led to an increase in the concentration of indoor pollutants. "Sick building syndrome (SBS)" and "Sick house syndrome (SHS)" are worldwide problems. Also, the number of complaints about indoor air pollution caused by VOCs (Volatile organic compound) and HCHO (Formaldehyde) has increased. It is important that evaluating and understanding emission of indoor air pollutant from building materials. The object of this study was to evaluate emission test method for flooring such as wood based flooring, carpet tile, rubber tile, PVC sheet and tile, and to determine emission of TVOC and form-aldehyde. The quantity of TVOC and carbonyl compounds emission were sampled and measured by Tenax TA and gas chromatography/mass spectrometry (GC/MSD), 2,4-DNPH cartrige with ozone scrubber and high performance liquid from flooring. The TVOC concentration emitted from carpet tile was ($7.419\;mg/m^2 h$) the highest among 5 groups of test materials. In wood based flooring and PVC tile, the emitted concentration of toluene was high. And the dodecane emission was highest in carpet. The concentration of TVOC decreased by an increase in emission test period. After 7 days, the concentration of TVOC from floorings were about 50% below of the concentration at the first day. TVOC emission from wood based flooring, carpet tile, rubber tile, PVC sheet and tile were decreased in 28 days and remained steady after about 15 days. The concentration of formaldehyde emission from floorings showed extremely low.

  • A methodology is applied to identify tile learning trend related to the safety and availability of U.S. commercial nuclear power plants. The application is intended to aid in reducing likelihood of human errors. To assure that tile methodology ran be easily adapted to various types of classification schemes of operation data, a data bank classified by the Transient Analysis Classification and Evaluation(TRACE) scheme is selected for the methodology. The significance criteria for human-initiated events affecting tile systems and for events caused by human deficiencies were used. Clustering analysis was used to identify the learning trend in multi-dimensional histograms. A computer rode is developed based on tile K-Means algorithm and applied to find the learning period in which error rates are monotonously decreasing with plant age.

  • Total organic carbon (TOC) derived from organics is one of tile possible contamination in the reactor water system and causes of pH change and high conductivity levels. Measurements of total dissolved oxidizable carbon were carried out and its contribution to conductivities at elevated temperature was studied by using tile thermodynamic equilibrium analysis in carbonic acid system. The calculated conductivities were in good agreement with tile levels observed for tile formation of carbonic acid from salicylic acid solution.

  • 미래에는 생활환경 주변에 다양한 용도의 대형 디스플레이 장치가 설치되고 사용자들에게 편리한 상호작용적인 서비스를 제공할 것으로 예측된다. 그러나 대형 디스플레이는 그 물리적 크기 때문에 기존의 마우스와 키보드와 같은 장치로는 효과적인 사용자 인터랙션이 쉽지 않다. 최근 이런 대형 디스플레이를 위한 인터랙션 방법에 대해 많은 연구가 수행되고 있다. 본 논문에서는 타일드 디스플레이 기반의 인터랙티브 응용프로그램 개발을 지원하는 iTILE 프레임워크와 이를 활용하여 테이프 스위치와 적외선 카메라 텐저블 인터페이스 입력장치를 사용한 응용프로그램에 대해 기술한다.

  • LOD(Linked Open Data)는 온톨로지에 기반하여 구조화되고 링크드 데이터 원칙에 의거하여 식별, 연결, 접근되는 RDF 트리플들로 구성된다. 이러한 LOD 데이터집합의 공개는 LOD 클라우드의 확장으로 이어지며 궁극적으로는 데이터 중심적인 웹으로 진화한다. 그러나, 존재적으로 동일한 개체들이 여러 LOD 데이터집합들에 걸쳐 서로 다르게 식별되는 경우 이들간의 동일성을 파악하여 신뢰적인 연결을 제공하는 것은 어려운 작업이다. 이를 위하여 본 논문은 신뢰향상적 연결성 평가(Trustworthiness Improving Link Evaluation: TILE) 기법을 제시한다. 보다 신뢰적인 연결성 평가 결과를 도출하기 위하여 TILE은 4단계로 진행한다. 우선, TILE은 LOD 데이터집합의 문법요소들이 가지는 추론적 특징을 고찰하여 잠재적으로만 존재하고 있던 사실들을 RDF 트리플들로 실체화하여 이를 데이터집합에 보강한다. 두 번째 단계에서 지정한 술어의 목적어 값을 비교하여 평가를 수행하며 세 번째 단계에서 RDF 트리플의 술어부가 지니고 있는 문법적 특성을 주어서술적/어휘정의적 관점에서 평가한 후 이를 두 번째 단계의 결과에 추가 반영한다. 이 과정에서 TILE이 고찰하는 문법적 요소들은 LOD 클라우드를 구축하기 위하여 W3C가 제시한 언어인 RDFS, OWL, OWL2 모두를 망라한다. 마지막으로, LOD 데이터집합 공개자로 하여금 연결성 평가결과를 검토하여 재평가 실시 혹은 연결확정을 결정하도록 함으로써 공개하는 데이터의 연결성이 가져야 하는 신뢰성에 공개주체의 책임이 반영되도록 한다.
